RemarTcs. There are five specimens in the British Museum from 
the Upper Cretaceous of Lebanon, exhibiting the mandibles asso- 
ciated with the shell, and in each example there is a brownish 
stain surrounding the mandible, caused, no doubt, by the decay of 
the animal matter. The beaks are all exposed upon the surface of 
the cast of the ventral aspect of the body- chamber of the shell. 
The largest mandible (figured supra, p. 305, fig. 67, cT), when per- 
fect, would have measured about 5 lines in length, with a greatest 
breadth of about 3 lines. It is attached to a specimen (JSTo. C. 2918) 
which is about 3| inches long (allowing for compression) and 2 to 
2| inches broad. Some idea may thus be formed of the relative size 
of these fossil mandibles to the shells they belonged to.
